Grim is more powerful than he lets us see
powerless without his scythe?
it was stated multiple times that his scythe is an ancient, powerful tool and, that it is often stolen from him. but is he really that powerless without it?
in ep Look Alive!, we just saw that he can fly. he emphasizes it in ep Dad Day Afternoon. in ep Billy Ocean, when searching Mandy and he are searching for Billy, he's sea-sick and seems to be helpless, but, after he loses his patience, he changes magically into his death robe, flies above the sea, and opens it with his scythe, instantly spotting the whale which swallowed Billy. pretty precise, huh?
in ep Tickle Me Mandy, Attack of the Clowns, Complete and Utter Chaos! (Billy Gets Dumber!), Toys Will Be Toys, and He's Not Dead, He's My Mascot he can bring inanimate objects to life: New Mandy, a clown head, a magic banana a burrito, Billy's toys, and Fluffy Cat, respectively. but he gives life to New Mandy... without his scythe.
he can send souls to the afterlife without it, proved in ep Billy & Mandy's Jacked-Up Halloween. he just uses a feather.
in ep Dumb Luck, his saliva has supernatural powers on its own.
in ep Nursery Crimes, he sends them to the storybook without his scythe. maybe the storybook itself had supernatural powers, but only Grim's words seemed to control it. Grim said that the storybook's rule is that the ones who got there, only get out if the stories are finished, but: Mandy finished all the stories, but they still remained stuck, because Grim fell asleep.
in ep My Peeps, he has fun running away from Billy, and likes having some smoothies with Mandy (like in the end of ep Keeper of the Reaper), but when he stops having fun and is simply just annoyed, uses magic without his scythe to restrain Billy, and levitates his scythe back to himself with ease.
in ep Sickly Sweet, he only uses his finger to turn a flower into a flesh-eating abomination. and: he destroys Mandy's cookies with the fire in his eyes (poor Mandy).
in ep Five O'Clock Shadows, he uses telekinesis. also in ep Aren't You Chupacabra to See Me? and other instances.
ep Bully Boogie. remember the rubber duck? ooh!
in ep Billy & Mandy Save Christmas, Nancy took hIS scythe, but they weren't in any danger. he could whistle and call his scythe whenever he wanted to.
he's not powerless without his scythe. when he is depressed in ep The Incredible Shrinking Mandy and just can't put on his usual mask, he snaps his fingers and makes Billy's monkeys to just vanish away.
did you see how did he "redecorated" Atrocia's studio in ep The Grim Show?
can be taken out by mortals or even immortals?
in ep Look Alive!, we learned that he can fly, so why doesn’t he just fly to the tree in ep Druid, Where's My Car?, or fly around in the christmas episode when he's fighting off vampire elves with Mandy?
in ep Which Came First?, he seems to be helpless against the mutant chickens as they were "created by science", hence "out of his jurisdiction", and runs from the chickens just as B&M does. but, in the end, he still isn't helpless when he summons a shield. Billy even notices this and says:
Billy: hey, Grim! you know how did you do that force field thingy that kept the volcano from cooking us?:D
Billy: why didn't you use it to save me from the chickens?:D
Grim: because, Billy:) I don't like you:)
in ep Dream a Little Dream (even in a dream), and ep Happy Huggy Stuffy Bears, we saw that he can use his scythe for actual cutting, reaping, and not just for magic, but still, he often pretends that his scythe is useless with various excuses.
in ep Fear and Loathing in Endsville, his scythe's battery is empty.
in ep Billy & Mandy Save Christmas, his scythe is frozen because of the cold.
in ep Billy & Mandy's Jacked-Up Halloween, it is stated by Billy that, his head, indeed, can be taken off, but Jack also states that his head remains off when it is taken off with the Grim Reaper's scythe, indicating that he could, indeed, die. but, in ep The Incredible Shrinking Mandy, Billy just cuts his head off by accident, and Grim just makes his skull hop back to his body.
in other instances, like in ep Wild Parts, he seems to have a hard time getting his skull back to his body, yet in ep The Incredible Shrinking Mandy, he does it with ease.
in ep Grim vs. Mom, after he was beaten up by Gladys, he needs help from B&M to reassamble his body from his bones, but in Big Boogey Adventure, it is revelaed that he can disassamble and reassamble himself anytime he wants.
ep Billy and Mandy Moon the Moon.
Grim: alright, enough of dis! by da power of da underworld, I have da power
Mandy: six seconds to live, and now you decide to act?!
Grim: what can I say?:) I love da drama:)
being the Grim Reaper with unlimited supernatural power must be restrained, and that's why the Underworld Court and Father Time exists. or, are they?
in ep Jeffy's Web, he summoned Jeff's life-timer hourglass out of thin air, and added life-sand into it, also out of thin air; despite life-sand described in ep The Halls of Time as something manufactured there, supervised by Father Time and, that the hourglasses are stored there, are just accessible from there and Grim had to rush back to there in that episode… is he playing with us
can't harm Billy and Mandy in any way?
he can't harm B&M in any way, stated in ep Hurter Monkey / The Incredible Shrinking Mandy / etc., but, maybe he just doesn't want to.
in ep The Really Odd Couple, they seem to be taking him a bit more seriously than usual when he loses his temper. maybe they know when he's serious?
in ep Terror of the Back Knight, he gets the chance to take off Billy for good as Billy himself challenged him to a duel, so it would be a fair opportunity to just take his head off. instead, he just plays with him dramatically, having fun. "it's overr, IT'S OVERRR~ ohh, it's over? xD"
he was just punching Billy with Billy's ripped off arms in ep Sickly Sweet and,
he even punched his nose off with his own bony hand in ep My Fair Mandy.
has to obey Billy and Mandy at all costs?
"Grim. you know what happens when you say don't, won't or can't to me." –Mandy
he seems to obey them against his will, but still, he can't be coerced when he really doesn't want to do something.
in ep Chicken Ball Z, Mandy asks him to give him powers with which she can win the karate tournament, he straight-up refuses, and Mandy has to look for other ways.
can't leave Billy and Mandy for good?
he has several chances to leave them, but he doesn't take any of it.
in ep Fiend is Like Friend Without the "R", Nergal kidnaps B&M, hence he can be free. at first, he seems to take on the chance gladly, but his non-existing heart softens when seeing Billy's drawings of him, so he goes back to save them.
the scenario reoccurs in ep Circus of Fear where Dr. Fear kidnaps them to be the human attractions to his circus: this time, for saving them, he gets the nudge from Gladys, to which he doesn't even have to obey: he is best friends forever with B&M, not Gladys; despite this, he goes.
in ep Scythe 2.0 is after B&M and, this time, being with them for so long, Grim doesn't even need a reminder to act: the moment he gets the call from Scythe 2.0 that she will take the kids' heads, he gets worried; then he saves them on his own.
in ep Test of Time, it is revealed that he has a remote control which can rewind time so, why didn't he just rewind before he lost or, even accepted the bet to B&M?
in ep Billy Gets an 'A', it is revealed that he can go back in time even with his scythe, and he does so with Mandy, even going as far as trying to prevent Billy's birth O.O but… he didn't think of this before. it hasn't occurred to him before, and later on, he doesn't seem to even consider it.
exemption: in ep Wishbones, he has a chance to wish for freedom, but he doesn't, as wishes always backfire. but, in the end credits, we can see that he did try it, but, his wish, indeed, backfired.
in ep Billy and Mandy vs. the Martians, he gets a chance, again, to get away, but still, Billy convinces him to stay. after his speech, he feels bad, and goes on to save Mandy from the zombies. (ohh, not because of her! of course not! he plays the tsundere.)
honestly, Grim is just playing. he's an immortal being, who is bored, and he doesn't have to prove anything. he's not a fool, he's fooling around. and he's not bound to Billy and Mandy solely by just his given word. he really is their friend.
